ST3222C - RS-232 drivers/receivers

Download the ST3222C datasheet PDF. This datasheet also covers the ST3222B variant, as both devices belong to the same rs-232 drivers/receivers family and are provided as variant models within a single manufacturer datasheet.

Description

The ST3222 is a 3 V powered EIA/TIA-232 and V.28/V.24 communications interface with low power requirements and high data-rate capabilities.

ST3222 has a proprietary low dropout transmitter output stage providing true RS-232 performance from 3 to 3.6 V power supplies.

Features

  • 300 µA supply current.
  • 250 kbps minimum guarantee data rate.
  • 6 V/µs minimum guarantee slew rate.
  • Meet EIA/TIA-232 specification down to 3 V.

ST3222B ST3222C 3 to 3.6 V, low power, up to 400 kbps RS-232 drivers and receivers Features ■ 300 µA supply current ■ 250 kbps minimum guarantee data rate ■ 6 V/µs minimum guarantee slew rate ■ Meet EIA/TIA-232 specification down to 3 V Description The ST3222 is a 3 V powered EIA/TIA-232 and V.28/V.24 communications interface with low power requirements and high data-rate capabilities. ST3222 has a proprietary low dropout transmitter output stage providing true RS-232 performance from 3 to 3.6 V power supplies. The device requires only four small 0.1 mF standard external capacitors for operating from 3 V supply. The ST3222 has two receivers and two drivers. The ST3222 features a 1 mA shutdown mode that reduces power consumption and extends battery life in portable systems.
